A common yet undescribed MRI finding in newborns: posterior epidural space edema of the cervical and upper thoracic spine

Posterior spinal epidural space (PSES) is a fat-containing space. We noted numerous spinal MRIs demonstrating T2-hyperintense thickening of the cervical/thoracic PSES in early newborns, resembling epidural edema. Our aim is to describe the appearance/frequency of this finding and explore any associations with delivery.Retrospectively, 202 spinal/cranial MRIs, belonging to newborns within the first 2 weeks of life, were evaluated using sagittal...
